Common AmigaDOS commands

Dave Farquhar Retro Computing August 16, 2016June 28, 2019amiga, cmd, commodore, Digital Equipment Corporation, ramdisk, TEMP, TMP, unix, unix commands

The Amiga had a command line, or CLI. It was a rather powerful CLI, especially for its time. But there are a number of differences between AmigaDOS and other operating systems you may be familiar with. These are the common AmigaDOS commands and their equivalents from other operating systems like DOS, Windows, Unix or Linux.

I’ve never seen a primer that relates or cross-references Amiga commands to Windows and Unix. So I wrote one. I hope it helps you understand your Amiga better. Because Amiga is sometimes like Windows and sometimes it’s like Unix, I think it might. And maybe, just maybe, you’ll learn something you didn’t know about Windows or Unix too.

Commodore 64 vs 128

Dave Farquhar Retro Computing May 19, 2016October 26, 20221541, 1571, 1980s, 6502, amiga, apple, apple ii, c64, commodore, commodore 128, commodore 64, tape drive

Commodore introduced the Commodore 128 in 1985 as an upgrade path from the Commodore 64, the most popular model of computer of all time. The 128 addressed the 64’s biggest shortcomings while remaining mostly compatible with its hardware and software. That makes the Commodore 64 vs 128 a natural comparison, even more natural than comparing the 64 with the VIC-20.

The Commodore 128 was an extension of the Commodore 64, with more memory, a faster disk drive, a faster CPU, and 80-column video. It also featured a very high degree of compatibility, which helped both machines sell better.

Who bought Commodore

Commodore International went out of business in April 1994, after nearly a decade of declining revenue. But the company left a significant legacy, which leads to some logical questions. What became of Commodore? Who bought Commodore?

Commodore 64 vs VIC-20

Dave Farquhar Retro Computing December 7, 2015October 26, 20221541, 1980s, 6502, amiga, atari, atari st, commodore, commodore 64, jack tramiel, Microsoft Basic, MOS, power brick, public domain

How do you compare the Commodore 64 vs VIC-20?

The Commodore 64 and its predecessor, the VIC-20, look a lot alike, and the VIC-20’s design certainly influenced the 64. The 64 is the best selling computer model of all time, and I argue the VIC-20 was the first really successful home computer. The success of the two machines allowed Commodore to surpass Radio Shack as the sales leader in the computer industry. Yes, both Commodore and Radio Shack outsold Apple.

But even though the two machines are closely related, there are significant differences between them. It’s important to remember that in the 1980s, two years was a comparatively long time because the market was moving so fast. Plus, the VIC-20 was always supposed to be an entry-level machine. In 1982, the 64 was supposed to be fairly high-end. Let’s compare and contrast the two venerable machines.

Need a Commodore motherboard? Believe it or not you’re in luck

Dave Farquhar Retro Computing October 23, 2015October 20, 2015amiga, amiga os, commodore, commodore 64

Individual Computers is working on, of all things, a replacement Amiga motherboard that will fit in an Amiga 500 or Amiga 1200 case.

The board will use the AGA chipset that the Amiga 1200 used, but the board will be built using a modern process, modern materials, and as many other modern components as possible.

I miss the sound of a modem carrier

“I know this will sound crazy,” my boss said. “But I miss the sound of a modem connecting.”

I don’t think it’s crazy at all. That chirping was the sound of a hard-won victory, at least if you’re of a certain age.

Building DOS gaming PCs

The ultimate DOS gaming PC is a topic that I’ve seen come up in forums frequently, and that I’ve been asked directly a number of times. I guess since I published advice on running DOS games on Windows PCs on two continents, people figured I knew something about that. I guess I fooled them!

The trouble is that no single PC can really be the “ultimate” DOS game machine. Well, not if your goal is to be able to optimally run everything from early 1980s titles designed for the original IBM PC up to the last DOS version of Quake. I learned that the hard way in 1995 or 1996, even before Quake existed. Read more

How the Amiga could have lived to age 30 and beyond

Dave Farquhar Retro Computing July 25, 2015February 18, 20171980s, 1990s, amiga, amiga os, apple, atari, Bill Gates, commodore, commodore 128, commodore 64, IBM, intel, irving gould, jack tramiel, macintosh, Mehdi Ali, Microsoft Basic, MOS, motorola, nbc, os x

It was 30 years ago this week that Commodore released its landmark, long-time-coming Amiga 1000 computer–the first 1990s computer in a field full of 1970s retreads.

Yes, it was a 1990s computer in 1985. It had color and sound built in, not as expensive, clunky, hard-to-configure add-ons. It could address up to 8 megabytes of memory, though it ran admirably on a mere 512 kilobytes. Most importantly, it had fully pre-emptive multitasking, something that previously only existed in commercial workstations that cost five figures.

It was so revolutionary that even NBC is acknowledging the anniversary.

Being a decade or so ahead of its time was only the beginning of its problems, unfortunately.

Why this latest attempt to resurrect the Commodore brand will probably flop

Dave Farquhar Android, Retro Computing July 16, 2015August 3, 20171980s, 1990s, amiga, android, apple, commodore, dell, lenovo, motorola, Packard Bell

The Commodore brand is back again, this time on an Android smartphone. For a premium price, you get an Android 5.0 phone with the Commodore logo on it, preloaded with VICE and an Amiga emulator, which, between the two of them, emulate just about everything Commodore ever made, except, perhaps, the products that can be emulated with the Android calculator app.

But I don’t expect this attempt to be any more successful than earlier efforts to resurrect the brand.

If I were buying an SSD today

Dave Farquhar Hardware April 29, 2015April 26, 2015amiga, commodore, kingston, micron, PNY, samsung

SSD pricing continues to be competitive, and if I were buying an SSD today, I would have a tough decision ahead of me. The Crucial BX100 would be the obvious choice, with its good speed, super-low power consumption, and attractive price, at $99 for the 250GB model and around $185 for the 500GB model.

But there’s an underdog: the PNY CS1111. Bear with me on that one: It’s a little slower than the Crucial, but costs 15% less.
